A simple and reproducible UV- spectrophotometric method for the quantitative determination of Tannic acid in Bhuvnesvara vati (BV) were developed and validated in the present work. The parameters, precision, accuracy, Limit of Detection and Limit of Quantitation were studied. In this present study a new, simple, rapid, sensitive, precise and economic spectrophotometric method in ultraviolet region has been developed for the determination of Tannic acid in laboratory ayurvedic formulation of Bhuvnesvara vati (BV). Each ingredient was purchased from the local market and identified morphologically and microscopically and compared with standard pharmacopoeial monograph. The concentration of tannic acid present in raw material is found to be 6.1%±0.27w/w in Emblica officinalis, 8.7%±0.31w/w in Terminalia belerica, 14.05%±0.29w/w in Terminalia chebula, 4.8%±0.94 in Aegle marmelus and 0.67±0.49 in Trichyspermum ammi and in three identical laboratory batch of Bhuvneshavara vati BV-I, BV-II and BV-III 4.90%±0.42, 4.79%±0.86, 4.85%±0.75w/w respectively with mean value 4.85%±0.53 w/w. Tannic acid has the maximum wavelength at 276 nm and hence the UV spectrophotometric method was performed at 276 nm. Tannic acid was found to follow beer lambert's law in concentration range 2-20μg/ml. The mean of %RSD value was found to be 0.399 with the mean standard error were 0.275.The content of Tannic acid in ayurvedic formulation was determined. The results of analysis have been validated statistically and confirmed the accuracy of the proposed method. Hence the proposed method can be used for the reliable quantification of Tannic acid in herbal formulations.

The anti-synchronization of chaotic systems discusses a pair of chaotic systems called master and slave systems and seeks to design controllers (connected to the slave system) so that the states of the synchronized systems have asymptotically the same amplitude but opposite signs, i.e. the sum of the respective states of the master and slave systems can be made to converge to zero asymptotically with time. Synchronization and anti-synchronization of chaotic systems have several applications in science and engineering. In this paper, we design of active and adaptive controllers for achieving anti-synchronization of the states of identical Rabinovich chaotic systems (1979) having two parameters a and b. We apply active control method for the anti-synchronization of Rabinovich systems when the system parameters are known and prove the anti-synchronization result by Lyapunov stability theory. We apply adaptive control method for the anti-synchronization of Rabinovich systems when the system parameters are unknown. We use adaptive control theory by implementing estimates of unknown parameters and derive parameter update law for estimates of unknown parameters with the help of Lyapunov stability theory. We have illustrated the main anti-synchronization results for Rabinovich systems for active and adaptive controller designs with MATLAB plots. © 2013 IEEE.

Popularity of electronic business has changed the way people are transacting businesses around the globe. People are engaged in online businesses (like buying, selling, promoting or collaborating) without any physical or face to face contact with the trading partners. Correspondingly, the concept of reputation has become an as important pillar of the electronic business to provide some level of assurance about the quality of the traders as well as their products and services. In this scenario, online feedbacks have emerged as a valuable tool in reputation management and help in making a choice for the best quality online trading partners. Further, there is a strong need for the e-business companies to change their strategies and decision making process to build and manage their reputation via online feedbacks. In this paper, the reputation and reputation management through online feedbacks have been discussed with a specific focus on the electronic business (e-business). This paper examines the prevailing reputation models, which are based on online feedbacks and are used by the companies. Specific examples and cases have been added to highlight the present day industry scenario. Copyright © 2016, IGI Global.

The present study was aimed at assessing efficacy of 3 harvesting methods on the quantity and quality of oocytes recovered for assisted reproduction procedures in goat. The average total number of oocytes recovered per ovary was significantly higher by slicing (6.54±0.39) and puncture (6.59±0.39) than by the aspiration method (4.09±0.19). However,the percentage of good quality oocytes was higher in the puncture method (71.56%), compared to the aspiration (71.27%)or slicing (61.61%) methods. The oocyte recovery was significantly lower in CL containing ovaries than that of ovaries without CL in aspiration (2.92 vs 4.57), puncture (5.89 vs 6.78) and slicing (5.40 vs 7.02) methods. However, the presence of CL did not affect the oocytes ability to reach the MII stage (75.31% vs 76.67%). The side (right or left) of the ovary not showed any significant effect on mean of total oocyte recovery and other grades of oocytes. However the large sized ovaries were yielded significantly higher number of oocytes than smaller ovaries. The results showed that the rates of COCs that reached the metaphase-II (M-II) stage were 79.88, 78.09 and 72.63% in aspiration, puncture and slicing techniques, respectively. The maturation rate was significantly lower in slicing method. The oocytes obtained were matured and parthenogenetically activated in vitro using ionomycin and 6-DMAP. There was no significant difference in the subsequent percentage of cleavage and development to blastocyst stage in vitro between the three methods of oocyte harvesting. It was concluded that though oocyte recovery, and in vitro developmental rates did not vary significantly between puncture and slicing methods, yet puncture method was found to be superior due to low debris content and recovery of more number of culture grade oocytes. Oocyte recovery by aspiration from small sized ovaries was difficult due to less number of visible follicles. Puncture method can be used as an alternative to slicing and aspiration for oocyte recovery in goat.

Fault tolerance techniques enable a system to perform tasks in the existence of faults. In a distributed system, hardware and software components are located at network computers and communication and coordination of their action is done by only passing messages. Mobile computing is progression of wireless network technology and portable information appliances such as laptops, handheld devices, PDAs etc. In the state based approach for recovery, known as snapshot, the entire state of a process is saved. When a recovery point is established, recovering a process involves reinstating its saved state and resuming the execution of the process from the state. Exhaustive research work has been carried out on designing efficient state based schemes for fault tolerance. In mobile distributed computing, due to mobility of MHs and limitations of wireless networks, there are new issues like mobility, catastrophic failure, limited battery life, low bandwidth, disconnections etc. That complicate the design of the snapshot algorithms. Recently, more attention has been given to providing state based approach of recovery for mobile systems. This paper surveys the algorithms reported in literature for introducing fault tolerance in mobile distributed systems and extension of it. © 2015 IEEE.

Objective: An appropriately designed sustained-release drug delivery system can be a major advancement towards solving problems concerning controlling the rate of drug delivery. Matrix tablets are an interesting option when developing an oral sustained release formulation. The present study focuses on oral sustained-release dosage forms and types of various polymers used to formulate matrix tablets of Zaltoprofen. Water soluble polymers such as polyvinylpyrrolidone may be used to increase the dissolution rates of poorly soluble drugs. Hydroxy Propyl MethylCellulose (HPMC) is cellulose ether which may be used as the basis for hydrophilic matrices for sustained release oral delivery. Polymer backbone of different grades of HPMC, microcrystalline cellulose in different combinations and ratios may be prepared for the treatment of post-trauma chronic inflammation.The aim of study is to develop a once daily sustained-release tablet dosage form of Zaltoprofen by optimizing the release profile of drug through varying the composition of polymers. Method: Sustained release tablets of Zaltoprofen were prepared by wet granulation method using water soluble polymers such as polyvinylpyrrolidone and different grades of cellulose ether like HPMC both intra and extragranularly. Polyvinylpyrrolidone (PVPK30) dissolved in isopropyl alcohol was used as the granulating agent. Various grades of microcrystalline cellulose (Avicel) were used in granules and matrices to control the release rate. Tablets were subjected to physicochemical characterization such as thickness, hardness, friability, weight uniformity, drug content, disintegration time, in vitro drug release, and stability studies. The kinetics of the dissolution process was studied by analyzing the dissolution data using five kinetic models, the zero-order equation, the first-order equation, the Higuchi square root equation, the Hixson-Crowell cube root law and Korsmeyer-Peppas equation. Result and Discussion: All formulations were found to be satisfactory when evaluated for thickness, weight uniformity, hardness, friability, drug content uniformity and in-vitro drug release. The in vitro drug release in optimized formulation C11 was found to be 99.23% in 24 hours. C11 also showed satisfactory hardness (6.55±0.0614 kg/cm2), friability (0.495%±1.258), drug content (99.47%±0.0565) and weight variation (402.65±0.3118 mg). The analysis of the dissolution kinetic data shows that it follows the first order kinetics and the release process involves erosion/diffusion and an alteration in the surface area and diameter of the matrix system, as well as in the diffusion path length from the matrix drug load during the dissolution process. © RJPT All right reserved.

Ascorbate peroxidase (E 184.108.40.206) acts as primary key component of plant defense against photo protection and photo-oxidative stress. Chloroplastic (APX) located in the thylakoid membrane (tAPX) and stroma (sAPX) have been thought to be key regulators of intracellular levels of H2O2. Therefore, it is of interest to study thylakoid membrane bound SlAPX from Solanum lycopersicum (tomato, a fleshy fruit). However, a structure model is not yet solved for tomato thylakoid membrane bound SlAPX. Hence, a homology molecular model of SlAPX6 from S. lycopersicum was constructed using a template structure (PDB ID: 1APX) from Pisum sativum. The model was further assessed using accessible surface area (ASA) calculations to identify surface residues for further characterization of active site regions. We further characterized the active site regions in the enzyme for functional inference. This information provides insights for the understanding of photo protection and photo-oxidative stress tolerant in S. lycopersicum during flower development and fruit ripening.
